I'm updating one of my games, changing it to free and adding Ad support via the Metro plugin.
I have never had the game lock up in my tests via the simulator or desktop. The App Certification passes the app with 0 issues. However the last 2 times I uploaded to Microsoft it fails stating the game locks up. The only thing I did to the game was add the Metro plugin.
Off course they don't tell me where the game is locking up. Any advice?
